DAYZ

[Midnightclub]

Essentially DayZ (the standalone game) is built on the Arma 2 engine and the DayZ mod, not a huge fan of the standalone personally as it has less features than the mod it was built on.

We (Me, WingNutz and a few others) play Arma 3 with the exile mod at the moment, no zombies but everything else is pretty much the same, but you get random missions, roaming AI, helicopters, cars etc.. and the graphics are miles ahead of Arma 2/DayZ. You still get to play the Chernarus map, there's also a few others which are around 275 km2 each.

Best way to keep your loot is start base building and get a safe.
